5A molecular sieve:

5A molecular sieve can adsorb any molecule smaller than the pore size, which is generally called calcium molecular sieve. In addition to the functions of 3A and 4A molecular sieves, it can also adsorb C3-C4 normal alkanes, chloroethane, bromoethane, butanol, etc. It can be used for the separation of normal isomers, pressure swing adsorption separation and co adsorption of water and carbon dioxide.

This sieve is absorbed by substances at the molecular level. It can absorb up to 22% of its body weight. Its adsorption principle is similar to that of chromatography, except that it does not change the molecular combination of substances.

1. Natural gas drying, desulfurization and CO2 removal;

2. Separation of nitrogen and oxygen, separation of nitrogen and hydrogen to produce oxygen, nitrogen and hydrogen;

3. Petroleum dewaxing, separation of normal hydrocarbons from branch hydrocarbons and cyclohydrocarbons.
